This review is a small part of our Best Mountain Bike Lights feature, where we tell you the three best lights - plus eight others to consider - after testing 24 different sets of lights.
If you’re looking for maximum punch for your pound – or beam for your buck – in terms both of weight and cost, Gloworm’s updated X2 light is a knockout.
The tiny twin-LED unit comes with a flood and spot lens that give a very focused beam with a lot of intense light where it does hit but dramatic fall-off at the edges. You can fit two flood (or spot) lenses to tune the beam but it works great as a helmet light in its default set-up.
There’s a neat remote control switch that scrolls between high, medium and low – or medium and low, depending on which programme you choose – which we found very useful.
The thermal throttle kicks in faster than on most lights, which explains long run times in the workshop and on the trail, but there’s enough juice in the hard-shell battery to last most rides at full chat.
